CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 334,962, dated January 26, 1886.

Application filed November 20, 1885. Serial No. l83,385. (No model.)

T0 all 1071/0711, it may concern:

Be it known that I, EUGENE L. MA'r'rnsoN, a citizen of the United States, residing at W'ever, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in OarOouplings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a perspective view of'a car-coupling embodying my improvements. Fig. 2 is a Sectional view through the line :l: a: of Fig. l. Fig. 3 is a similar view through the line y y of Fig. 1. Fig. 4is a detail ofthe holding-jaw E and its connections.

My invention relates to car-couplings adapt ed to automatically couple the cars coming together, and to be uncoupled without passing between the cars; and my invention consists in the construction and combination of devices, which will be hereinafter' fully described and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner' in which I have carried it out. y

In the said drawings, A represents the body ot' a railway-car, and B the ordinary form. of d raw-head provided with the usual coupling Upon each side of this draw-head B, and secured thereto, or forming a part of the same, it' desired, are supplemental draw-heads O and D, one of which, D, has a flaring mouth for the reception and guidance of a couplinglink held Within the draw-head C of the ap proaching car. This latter draw-head O is provided with a coupling pin, c, a shaft, E,

tween the jaw and the front portion of the drawhead by means of the weighted lever before described. The lower face ot' the drawhead O may also be provided with grooves e, for more securely holding the link in its normal position, it being retained in the drawhead by the usual coupling-pin, as shown.

The draw-head D, as before stated, has a wide flaring mouth to receive the link d in a draw-head similar to C, attached t'o the carto be coupled. A transverse shaft, D, passes through that portion of the draw-head just beyond the llaring mouth, and is secured to and operates a suitable gate, D", which sustains upon its top edge a eouplingpin, g, which,when the gate is pressed downward by the link d on the 4approaching car, immediately releases said pin g and permits it to drop through a perforation, h, in the gate and into the opening h', usually found in draw-heads, thereby securing the link and coupling the cars together.

The shaft D has upon its outer end a weighted lever, G, which, when the pin g is withdrawn from its position in the draw-head and the coupling-link removed, draws the gate upward,when the pin g is permitted to rest upon the top edge ofthe same and be held in that position until another link forces the gate from its normal position and enables the supported pin to drop to secure the link.

The means operated from the outside of the car for releasing the pin g and guiding it until it finds its seat upon the edge or' the gate consist, essentially, of a bar, Z, secured to and projecting from the upper surface of the draw# head, and a sliding plate, 1n, provided with an arm, n. It will be observed the coupling-pin g passes throughaperforation, n', in the arm n,

and the said arm is attached to a chain, p, or d equivalent means,whose other end is secured to a shaft, H, mounted in bearings on the carbody, and projecting beyond the sides of the latter terminates in handles, which furnish readymeans for operating the pin and releasing the link. To prevent the sliding plate from having too great play or movement, a stop, r, is formed on the bar and prevents the pin from being entirely withdrawn from its draw-head.

IOO

From the foregoing description it is evident in the employment of my improvements that when the cars containing my triple drawheads are brought together the link attached to the draw-heads C ot' one car enters the drawheads D of the other, and thereby connects both draw-heads and securely couples the cars.

If a car containing my improvement is to becoupled to a car having a draw-head in which only the usual link and pin are used, the central drawhead, B, only would be used, and the manner of coupling would be similar to that now practiced, except that I may attach the bar and sliding plate and their operating mechanism to the drawhead, and there- -by make the coupling and uncoupling much safer than if the brakeman had to pass between the cars to accomplish thedesired object.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. ln a car-coupling, the draw-head C and 3. In a car-coupling, the draw-head1), provided with an opening, h, and the coupling pin g, in combination with a gate, D, for sup- 35 porting the pin, and having an opening, h, through which said pin passes when released,

a shaft, D', upon which the gate is mounted, and a weighted lever on the end of the shaft for returning the gate to its normal position 4o when the pin is withdrawn, substantially as herein described.

4. In a car-coupling, the combination,with a draw-head having an automatically-operating gate, of a coupling-pin supported upon 45 EUGENE L.- MAT'rEsoN.
